COMBUSTOR AND METHOD FOR DISTRIBUTING FUEL IN THE COMBUSTOR

摘要

PROBLEM TO BE SOLVED: To distribute fuel in a combustor.SOLUTION: A combustor 10 includes a plurality of tubes arranged in a tube bundle 22 and supported by at least one plate 24 that extends radially within the combustor, wherein each tube 20 includes an upstream end axially separated from a downstream end and provides fluid communication through the tube bundle. A flow conditioner 18 extends upstream from the upstream end of one or more of the plurality of tubes, and a radial passage extends through the flow conditioner. A method for distributing fuel in a combustor includes a step of making a working fluid flow through a flow conditioner that extends from a tube that is configured in a tube bundle comprising a plurality of tubes and that is supported by at least one plate. The flow conditioner includes at least one radial passage to impart radial swirl to the working fluid. The method includes a step of making fuel flow through an annular insert that is at least partially surrounded by the flow conditioner.
